Unclassified RIPE Cable/DSL/ISP
Summary
Bredband2 Stockholms Stadsnaet AB
residential cable isp sweden
The AS handle ASHPDC is held by Bredband2 Stockholms Stadsnaet AB.
What it's used for
- The address space carries residential customer traffic, evidenced by reverse DNS entries such as
customer-46-39-119-254.stosn.netandcustomer-145-14-119-254.stosn.net. - The network announces 60,416 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a local access network rather than a transit provider.
- Traffic consists of subscriber eyeballs for cable and DSL services in the Stockholm region, consistent with the operator's business model as a regional ISP.
Notable
- All registrants for the announced prefixes are listed as
Bredband2 Stockholms Stadsnaet AB, matching the AS holder. - Bredband2 acquired Stockholms Stadsnät AB, which operated the network under the STOSN brand, integrating its customer base into the Bredband2 portfolio.
- The inventory includes a mix of /19, /20, /21, and /22 blocks, with netnames ranging from
SE-HPDC-19930901toSE-HPDC-20141216, reflecting long-term address allocation.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 440 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
